摘　　要：探讨影响耐碱螫合分散性的因素,如烧碱质量浓度、耐碱螯合剂的用量、硫酸铁铵用量,以及添加耐碱螯合剂时的温度等,其应用优化的工艺条件为:30 g/L NaOH,5%螯合剂10 mL,2 000 mg/kg Fe^(3+)10 mL。该螯合剂于常温或60℃下加入时,其耐碱螯合分散性基本一致。Factors exerting influences on alkali-resistant chelating dispersion of chelating dispersants are discussed, such as dosages of caustic soda, alkali-resistant chelating agent and ammonium ferric sulfate, and the temperature for chelating agent addition. The optimum process is NaOH 30 g/L, 5% chelating agent 10 mL and 2 000 mg/kg Fe3＋ 10 mL, and the alkali-resistant chelating dispersion is the same when adding of chelating agent at room temperature and 60 ℃ respectively.
